Dust devils are pretty common on Mars – the Red Planet is, after all, a very dusty and windy place. What’s a bit more rare is capturing one of the whirling devils on film. That’s because they fade away nearly as quickly as they appear.

But in October 2019, NASA’s Mars Reconnaissance Orbiter managed to snap a photo of a massive dust devil in action, courtesy of the Mars Reconnaissance Orbiter’s High Resolution Imaging Science Experiment (HiRISE), a powerful camera that’s been snapping photos of the Martian surface since 2006.

NASA’s first glimpse of one of these dust storms came in 1971 when the Mariner 9 spacecraft — the first to orbit another planet — arrived at the red planet. Since then, we’ve seen quite a few of these dusty spectacles global storms: in 1977 (twice), 1982, 1994, 2001, 2007 and 2018.

In 2018, we lost the Opportunity rover to the strongest dust storm ever observed on Mars. It blotted out nearly all of the sun’s light for several weeks, turning day into night and preventing the rover from being able to charge its batteries. (Opportunity and its twin, Spirit, ran on solar power, as opposed to Curiosity and the Mars 2020 rover, which run on nuclear power.)

Martian dust storms are common, especially at specific times in the year, like during the southern hemisphere’s spring and summer. Localized storms tend to last a couple of days and can cover regions of the planet the size of the United States. But planet-encircling ones are a different story.

These massive, global storms are usually unpredictable, and can linger for months at a time. “We still don’t know what drives the variability, but the 2018 storm gives another data point,” says Scott Guzewich, an atmospheric scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, who’s a lead in NASA’s dust storm investigation.

Dust devils are rotating columns of air and dust that form when hot air from the surface rises. The current of air created forms a whirlwind, which can be useful for clearing off solar panels on spacecraft as they pass over.

As we move towards potential human missions we need to know how the dust will affect astronauts as well as their equipment. Understanding how often these phenomena occur will be extremely helpful for future missions.

During the dust storm of 2018, Curiosity was able to collect data about the storm, watching as its effects were felt half a world away from where Opportunity sat, hunkered down and hibernating.

Curiosity discovered that dust devils disappear during a dust storm, which happens to be when we need them the most. And they’re gone for several months afterwards as well. This is because the storm interrupts the wind-generating processes that spawn the dust devils.

According to Guzewich, understanding a global storm’s impact on dust devils is a crucial component in planning how to manage equipment during future Mars missions. “You need to be prepared to go a while before your next dust devil passes over and cleans you off,” he said.

Researchers at the University of Arizona recently published details on a newly photographed dust devil, which formed on the volcanic plains of Amazonis Planitia.

According to the HiRISE imaging team, the core of the dust devil is 164 feet (50 meters) wide, and probably about 2,32 feet (650 meters) tall. As massive as it sounds, there are even larger ones whirling around.

In March 2012, HiRISE took a photo of an active dust devil that was a whopping 12 miles (20 kilometers) tall. But was only slightly wider than the most recent one, at just over 229 feet (70 meters) wide.

For the first time, humanity has a fleet of spacecraft orbiting Mars as well as one rover roaming the surface right now (with two more to follow in the coming months). With their help, scientists will be able to better understand this puzzling phenomenon.

Tesla China has released a useful new accessory for the Model Y L, and it is free for some owners. With the accessory, the Model Y L effectively becomes a giant power bank that owners can use to power appliances when they are camping, or if their homes are hit by a power outage. 

Tesla Model Y L V2L adapter

Tesla China announced the rollout of the Model Y L’s AC external power adapter on social media platforms such as Weibo. As per the product’s advertisement, the Model Y L could provide up to 2,200W of power with its adapter, allowing it to support numerous appliances on the go. Of course, but could also be used to charge devices during power outages. 

Tesla China notes that the adapter’s current is 220V, and it also features an IP44 protection grade. Tesla notes that the adapter could operate at temperatures between -30℃ ~ +50℃. The Model Y L’s V2L functionality would not work if the vehicle’s battery is less than 10%, however. 

Tesla China’s official shop is selling its AC external power adapter for a reasonable price. The product could be purchased for RMB599, which is equivalent to $85. That’s a great price for an accessory that could make car camping sessions several times more convenient.

Free for early Model Y L owners

While the Model Y L’s AC external power adapter is priced reasonably at the Tesla China shop, the accessory is available for free for early owners of the extended wheelbase six-seat all-electric crossover. This was highlighted in a message that Tesla China reportedly sent to owners of the vehicle.

“Your Tesla account is eligible for a free Model Y L dedicated AC external power adapter. Please log in to the online store to add the adapter to your cart. Once the system verifies it correctly, the price will automatically change to 0 yuan before placing the order. We will send it to you via express delivery subsequently. 

“This free qualification is only for the first owner of the Model YL who did not receive an AC external power adapter at pickup, valid until February 28, 2026. Failure to place an order upon expiration will be considered as a waiver of eligibility. If there is a temporary shortage of goods, please be patient and we will reschedule the replenishment by the end of January 2026,” Tesla China wrote.

Tesla Cybertruck and Model 3 program manager steps down

The now-former executive played a central role in several of Tesla’s key milestones.

Published

Siddhant Awasthi, Tesla’s Program Manager for the Cybertruck and Model 3, has announced his departure after eight years with the company. Starting as an intern, Awasthi played a central role in several of Tesla’s key milestones, from the ramp-up of the Model 3 and Giga Shanghai to the launch of the long-awaited Cybertruck.

From intern to program leader

In a social media post, Awasthi described leaving Tesla as “one of the hardest decisions” of his life. He credited CEO Elon Musk, Tesla’s leadership team, and his colleagues for helping turn ambitious ideas into tangible vehicles. During his tenure, Awasthi contributed to Tesla’s global expansion and the evolution of its vehicle electronics and wireless systems, culminating in the Cybertruck’s long-anticipated rollout in late 2023.

He noted the intensity and innovation of his Tesla years, calling the experience “a thrilling journey” that shaped his career before the age of 30. “It’s been an absolute privilege,” he wrote, adding that working with “rockstar colleagues” made even the most demanding days worthwhile.

Tesla’s leadership transitions

Awasthi’s departure comes as Tesla continues to scale global operations and prepare for major product updates, including next-gen vehicle platforms and software-driven improvements. Despite stepping away, Awasthi voiced confidence in Tesla’s future. “I’m confident Tesla will nail its next big mission,” he said, highlighting his belief in the company’s capacity to deliver breakthrough products and improve safety for drivers worldwide.

“This decision wasn’t easy, especially with so much exciting growth on the horizon. Tesla vehicles are incredibly complex systems that often don’t get the credit they deserve, but I’ve witnessed firsthand how they’ve changed lives—for our customers, my friends, and my family—adding real value and, above all, improving safety. I’m confident Tesla will nail its next big mission (especially after last week), and I’m truly excited for the next chapter of my life,” the former Tesla executive wrote.

Tesla is launching a crazy new Rental program with cheap daily rates, giving people the opportunity to borrow a vehicle in the company’s lineup with an outrageous number of perks.

This week, Tesla launched its in-house Rental program that will give people a vehicle for between three to seven days, with prices varying and starting at just $60 per day.

However, there are additional perks that make it a really great deal, including Free Supercharging and Free Full Self-Driving (Supervised) for the duration of the rental.

There are no limits on mileage or charging, although the terms do not allow you to leave the state you are renting.

Tesla wrote in an email advertising the program:

“Rent a Tesla and see how it makes every errand, commute, and road trip more fun. While it’s yours, try Full Self-Driving (Supervised) and control and monitor your vehicle with the Tesla app. 

Schedule your rental for three to seven days starting at $60 per day (plus taxes and fees) and charge for free at any Tesla-owned Supercharger.

Order your own Tesla within seven days of your rental to get up to a $250 credit toward your purchase.”

Tesla has long adopted the mentality that butts in seats will sell cars, and for the most part, it is a great strategy. Driving a Tesla is different from owning and driving a combustion engine vehicle; it truly feels as if you are in a car from the past when you get back in an ICE car.

This strategy could be looked at as more of a way for people to experience Tesla ownership than anything.

Although some might use it as a typical rental program that will see it be a cool way to drive without putting miles on a personal car, most will use it as the 48-hour test drive was designed for, which is a short-term way to experience EV ownership.

Tesla is only offering this program at a handful of locations currently, including San Diego and Costa Mesa, California.
